The projected increase in world energy consumption within the next 50 years, coupled with
low emission requirements, has inspired an enormous effort towards the development of …

We present a critical review that encompasses the fundamentals and state-of-the-art
knowledge of barium titanate-based piezoelectrics. First, the essential crystallography …

Piezoelectric materials convert mechanical energy into electric energy, and vice versa. They
have been applied in many critical fields, such as motor vehicles, medical devices, the …

Electric field-induced transformations occur in a myriad of systems with a variegated
phenomenology and have attracted widespread scientific interest due to their importance in …

Antiferroelectrics (AFEs) have a great potential for modern electronic devices by virtue of the
large strain during the antiferroelectric-to-ferroelectric (AFE-FE) phase transition under …

BaTiO3-based lead-free piezoelectric materials have long been known as “a mediocre class
of piezoelectric materials.” However, they have seen significant renewed interest in recent …

For high-resolution powder diffraction in material science, high photon energies are
necessary, especially for in situ and in operando experiments. For this purpose, a multi …

Neutron powder diffraction was used in operando to determine the macroscopic strain and
piezoelectric coefficient as a function of applied electric field in a technically relevant …

The electrocaloric effect (ECE) provides a novel route to realize eco-friendly cooling, whose
cooling efficiency could be further enhanced by integrating the positive and negative ECE …

Microstructural design is a widespread approach to tailor the properties of functional
materials with the size effect being an effective constraint that modifies physical phenomena …
